If you are using a seeded hard dates then soak them in milk overnight and remove seeds. I use soft dates so i just remove the seeds and don't soak.

1) Blend Dates, Sugar and milk into smooth paste, add oil and mix.2) Mix the all purpose flour and baking soda,add to the above paste slowly and mix.3) Preheat oven at 350F for 5 mins.4) Grease the cake pan and pour this mix and shake to form a flat surface and spread nuts on top.5) Bake the cake in oven upto 40 mins or until the knife inserted in the cake comes out clean.

Notes: You can make this cake without oil too if you want a low calorie version.
